摘　　要：指纹因其高度的个体差异性,是认定人身的重要依据。随着科技的进步,对汗潜指纹显现技术的要求也越来越高。瞬间胶作为一种快速、便捷的显现工具,在汗潜指纹显现中得到了广泛应用。本研究总结了前人针对四种瞬间胶(即“401”胶、“406”胶、“495”胶及“502”胶)在非渗透性客体表面汗潜指纹显现效果,结果表明:“406”胶对塑料板表面汗潜指纹的显现展现出较优效果;“495”胶显现玻璃板上的汗潜指纹效果更为突出;“401”胶较适用于塑料袋表面汗潜指纹的显现;“502”胶对皮革材料上汗潜指纹的显现效果最好。相对于其他瞬间胶,“502”胶的可使用范围较为广泛。Fingerprints are an important basis for identifying individuals due to their high individual variability.With the advancement of technology,the demand for sweat latent fingerprint display technology is also increasing.Instant glue,as a fast and convenient display tool,has been widely used in sweat latent fingerprint display.This study summarizes the effectiveness of four types of instant adhesives(namely"401"adhesive,"406"adhesive,"495"adhesive,and"502"adhesive)in displaying sweat latent fingerprints on the surface of non permeable objects.The results show that"406"adhesive has a better effect on displaying sweat latent fingerprints on the surface of plastic boards;The"495"adhesive exhibits a more prominent sweat fingerprint effect on the glass plate;401 adhesive is more suitable for displaying sweat fingerprints on the surface of plastic bags;502 adhesive has the best effect on revealing sweat fingerprints on leather materials.Compared to other instant adhesives,"502"adhesive has a wider range of applications.
